A Cambridge historian, Elizabeth Vogelsang, is found drowned, clutching a glass prism in her hand. The book she was writing about Isaac Newtons involvement with alchemy remains unfinished. When her son, Cameron, asks his former lover, Lydia Brooke, to ghostwrite the missing final chapters of his mothers book, Lydia agrees and moves into Elizabeths house. Soon Lydia discovers that the shadow of violence that has fallen across present-day Cambridge, which escalates to a series of murders, may have its origins in the troubling evidence that Elizabeths research has unearthed. As Lydia becomes ensnared in a dangerous conspiracy that reawakens ghosts of the past, the seventeenth century slowly seeps into the twenty-first, with the city of Cambridge the bridge between them.
